1st Samuel 17:8

5 And he had a head-dress of brass on his head, and he was dressed in a coat of metal, the weight of which was five thousand shekels of brass.

6 His legs were covered with plates of brass and hanging on his back was a javelin of brass.

7 The stem of his spear was as long as a cloth-worker's rod, and its head was made of six hundred shekels' weight of iron: and one went before him with his body-cover.

8 He took up his position and in a loud voice said to the armies of Israel, Why have you come out to make war? Am I not a Philistine and you servants of Saul? Send out a man for yourselves and let him come down to me.

9 If he is able to have a fight with me and overcome me, then we will be your servants: but if I am able to overcome him, then you will be our servants and do work for us.

10 And the Philistine said, I have put to shame the armies of Israel this day; give me a man so that we may have a fight together.

11 And Saul and all Israel, hearing those words of the Philistine, were troubled and full of fear.
